'Rick and Morty' Season 3 spoilers, air date: Mr. Meeseeks all set to return in upcoming episodes?

"Rick and Morty" fans who are eagerly waiting for the third season to premiere will be delighted to know that instead of the previous release date in 2017, Season 3 will now be aired this year.

In the recently concluded San Diego Comic-Con 2016, Dan Harmon, Cartoon Network's Adult Swim program creator, and Justin Roiland revealed that the production of "Rick and Morty" Season 3 was significantly difficult than the previous seasons.

Though the creators have already started working on the next episodes, they were not satisfied with the end results. They decided to make several changes in order to guarantee viewers' satisfaction.

As reported by Cinema Blend, Harmon said: "It's been harder this season. I watched the thumbnail animation of Episode 304 and I was ready to move forward with it and Ryan (Ridley) said 'we're not satisfied with it and we were already behind schedule... there's a weird higher calling there and it's not an endless perfectionism because you know when something finally clicks and you go 'this is a good episode of TV.' But it's not just me and I was very happy to find that out."

The production team of "Rick and Morty" is currently re-writing the scripts in order to make the dialogues and characters more appealing.

Meanwhile, several speculations suggest that one of the prominent characters from the series, Mr. Meeseeks, might turn up in one of the upcoming episodes. Meeseeks is a little blue creature who first appeared in Season 1 of "Rick and Morty" and since then, has become a fan-favourite.

Slash Film has reported that one of the episodes of "Rick and Morty" Season 3 might feature a spoof of "Star Trek: The Next Generation" and Meeseeks may appear on the show in the similar fashion to Dr. Seuss.
